Natural Evolution

How do you "win" at natural selection?

• survive

• go extinct

• survive & reproduce

Which of these is an example of natural selection?

• The largest animal in a population will have more opportunities for reproduction.
• Several species of organisms work together so that they all succeed.
• One species takes all the resources in an environment leaving none for others.
• Organism that are best suited to an environment tend to survive and reproduce more often.

Survival of the Fittest and Evolution were proposed by what scientist?

• Charles Darwin
• Albert Einstein
• Steven Hawking
• Isaac Newton

What word describes a trait that helps an organism survive in its environment?

• natural selection

• mutation

• camouflage

• adaptation

Which organisms are most likely to survive?

• those with an adaptive advantage

• the fastest
• the strongest
• the most domesticated (tamed)

Change over time

• Natural Selection
• Selective Breeding
• Homeostasis
• Evolution

Natural Selection is driven by a change in the environment and survival of the

• Earth

• Fastest

• Fittest

• Biggest

Because humans have determined which traits are favorable, dogs such as Chihuahuas are examples of....

• Artificial Selection 
• Natural Selection 
• Mutations 

Which of the following best illustrates natural selection?

• An organism with favorable genetic variations will tend to survive and breed successfully.

• A population monopolizes all of the resources in its habitat, forcing other species to migrate.

• A community whose members work together utilizing all existing resources and migratory routes.

• The largest organisms in a species receive the only breeding opportunities.

Why are advantageous traits more likely to be passed onto offspring?

• Because they are more likely to survive and reproduce.

• Because they come from dominant alleles.

• Because they come from recessive alleles.

• Because the organism knew it needed that trait, survives, and passes it on.
